Proof step 101 from proof kappa-RED1 (previous step)

〈RED1(t; tn2)〉 tn2 = tn0, 〈RED1(t .2; tn4): m 〉 tn4 = tn5, 〈RED1(t .1; tn3): m 〉 tn3 = none, 〈TOPRED(t; tn2): m 〉 tn2 = none, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn2): n0 〉 tn2 = tn1 ∧ 〈RED1(t; tn2)〉 tn2 = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ some(t .1 _ tn5 .t), tn5 ≠ none, ap(t), value(t .1) ⊦

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 100:
〈RED1(t; tn2)〉 tn2 = tn0, 〈RED1(t1; tn4): m 〉 tn4 = tn5, 〈RED1(t0; tn3): m 〉 tn3 = none, 〈TOPRED(t; tn2): m 〉 tn2 = none, ∀ n0, t, tn1, tn0. n0 < m + 1 → (〈RED1(t; tn2): n0 〉 tn2 = tn1 ∧ 〈RED1(t; tn2)〉 tn2 = tn0 ∧ tn0 ≠ tn1 → false), tn0 ≠ some(t0 _ tn5 .t), tn5 ≠ none, ap(t), value(t0), t = t0 _ t1 ⊦
